3 rounds (combination of technical and hr) , the rounds were easy, you just need to be confident and revise basic probability and statistics and practice puzzles from gfg and heard on the street. Also basic knowledge of coding will suffice.

Question 1
Probability puzzles. Toughest one I remember was... What is the expected number of Hamiltonian cycles in a random graph?
I applied online. The process took 4 weeks. I interviewed at J.P. Morgan (Londres, Inglaterra) in Nov 2018
Interview
I applied online, I received an invitation for some coding tests and after that there was a technical phone interview. The interview last an hour and it was technical, focusing on probabilities, statistics and some coding questions. The interviewer was helpful and gave me some hints for the answers. First, he asked me about my educational background and did some follow-up questions.
